Stian Andreassen:

Trying to run bootstrap in py3.3 (head). This runs fine in pypy default. But gives this under py3.3


```
#!python

pypy3.3 bootstrap.py
Downloading http://pypi.python.org/packages/source/d/distribute/distribute-0.6.49.tar.gz

Traceback (most recent call last):

    raise ImportError
ImportError

During handling of the above exception, another exception occurred:

...

Because it works fine with non-lzma implementation, I'd say it's a bug.
